How does word like academic & politic different from its -al form like academical & political? <-----Topic added to post by moderator (Florentia52)----->
There are many two-words corresponding to each other by this way. If we only talk about adjective, what is the difference of meaning of the two corresponding groups? Are there any rule about that?
